TE Connectivity KFM3 Series Installation Manual

Installation
1 - Always allow good ventilation clearances, 5mm left and right, 40mm above and 20mm below, around the unit in use to
prevent it from overheating. Also a 10-15 cm clearance must be kept when the adjacent device is a heat source.
2 - The appropriate mounting orientation for the unit is vertical, the input terminals at the bottom and output on the top.
Mounting orientations other than that, such as upside down, horizontal, or table-top mounting, is not allowed.
3 - Use copper wire only, and recommended wires are shown as below.

Lead(mm2 )
Note: Current each wire carries should be de-rated to 80% of the current suggested above when using 5 or more wires connected to the unit.
Make sure that all strands of each stranded wire enter the terminal connection and the screw terminals are securely fixed
to prevent poor contact. If the power supply possesses multi-output terminals, please make sure each contact is connected
to wires to prevent too much current stress on a single contact.
（4 - Use wires that can withstand temperatures of at least 80°C for KFM3-2420, 85°C for KFM3-2410.
（5 - Recommended wire strapping length is 5mm (0.197").
（6 - Recommended screwdriver is 4mm, slotted type.
（7 - The recommended torque setting for terminals is shown as below:
